DIY: Homemade Dish Soap

Choosing dish soap for me boils down to a question of economy versus ecology. According to The Naturally Clean Home, most commercial soaps are not soaps at all but harsh detergents “made from petroleum distillate, a toxic and nonrenewable resource.” Eek. The more environmentally friendly soaps, on the other hand, are often expensive. What’s an eco-conscious, design-minded individual on a budget to do? Make your own.

Turns out it’s easy and fun. Plus you can customize your concoction with the scent and container of your choice.

Ingredients

Ingredients and recipe adapted from Hello Natural.

• 1 1/4 cup distilled, filtered, or boiled water
• 2/3 cup unscented castile soap. Dr. Bronner’s Unscented Baby-Mild Castile Liquid Soap is $11.29 for 32 ounces.
• 1 tablespoon aloe gel (optional, for sensitive hands). Sky Organics’ Aloe Vera Gel is is $18.95 on Amazon.
• 1 1/2 teaspoons washing soda for extra grease-fighting power. Arm & Hammer Super Washing Soda is $9.89 for 55 ounces on Amazon.
• 1 teaspoon vegetable glycerin. NOW Solutions Vegetable Glycerine is $7.84 for 16 ounces on Amazon.
• 20 drops essential oil. I used pink grapefruit from Cambridge Naturals, my local store. NOW also makes Grapefruit Oil; $7.08 for one ounce at Whole Health.

Note: Many dish soap recipes call for vinegar, but vinegar shouldn’t be combined with castile soap. Because soap is a base, it reacts against acids such as lemon or vinegar, effectively canceling out the benefits of both and leaving you with a lumpy mess. (Read more here.)

Instructions: How do you make natural dish soap?

Note: I could go on for a while about essential oils. (If you’re curious, Crunchy Betty provides a comprehensive tutorial.) But I’ll just stick to the basics. First, make sure you use pure essential oils, not aromatherapy oils, which have been diluted with a carrier oil. Second, a word of caution: Essential oils are highly concentrated and can irritate your skin if you use too much, so stick to the recipe. Finally, because they smell “yummy,” it’s recommended that you keep them out of reach of children.
